RTN Therapy represents a comprehensive system of knowledge derived from historical industrial production of biological preparations made from natural ingredients. These supplements support cellular metabolism, tissue regeneration, and immune system harmonization.
What is RTN Therapy?
Historical Foundation
Recommended use of RTN products is based on thousands of real-world cases and the original medical formulations developed by Dr. Gabriel Urbánek, former chief physician at the Teplice State Therapeutic Institute.
Holistic Approach
We apply an individualized, holistic approach that respects the uniqueness of each person, while relying primarily on objective laboratory results to guide the selection and dosage of preparations.
Observational Studies
We continuously monitor the biological effects of RTN preparations through laboratory markers, focusing on their role in supporting metabolic balance, reducing chronic inflammation, and promoting long-term vitality.
RTN Preparations
Retisin (0.5 mg/ml)
Bovine blood extract rich in nucleotides (AMP, GMP, CMP), amino acids and oligopeptides. Supports aerobic metabolism and better energy utilization.
Lyastin (5 mg/ml)
Lipid components from bovine blood (phospholipids, lysophospholipids, sterols). Supports vasodilation, cell membranes, tissue regeneration and nervous system function.
Floristen (10 mg/ml)
St. John's wort extract with reduced hypericin and hyperforin. Helps reduce inflammation, provides antioxidant effects, and supports mental balance.
reInventedImmunology Study
Voluntary Participation
Voluntary use of selected dietary supplements (Retisin, Lyastin, Floristen, Silexil) with regular consultations with physicians or nutritional specialists.
Data Collection
Sharing health status, lifestyle, and subjective feelings (energy, sleep, activity) to analyze the influence of RTN preparations. Including biochemical results from laboratory tests.
Ethical Framework
Each participant signs an informed consent clarifying the purpose and course of the study. Participation does not establish entitlement to healthcare or treatment.

RTN Longevity Protocol
RTN Therapeutics combines advanced diagnostics with targeted natural formulations - Retisin, Lyastin, Floristen, and Silexil - to deliver precise healthcare solutions.
Specialized Diagnostic Panels
Our specialized diagnostic panels match specific health conditions with targeted RTN therapies, creating personalized treatment protocols — available exclusively to members under medical supervision, based on advanced biomarkers.
Each panel includes comprehensive markers such as HbA1c, Cystatin C, vitamin profiles, thyroid function, Omega-3 index, and homocysteine to ensure a holistic assessment. These are not included in the membership and are calculated separately on demand (if not available from existing laboratory tests supervised by a medical doctor).
